America's Test Kitchen Bread Recipe: No-Knead Artisan Crust in 24 Hours

America's Test Kitchen bread recipe delivers restaurant-quality no-knead crust with foolproof precision—no dough-making experience required. The secret lies in a 24-hour cold fermentation that develops deep flavor while keeping the texture impossibly tender. This method transforms simple pantry staples into an artisanal loaf with crispy crust and an open crumb structure that rivals bakery bread.

The process begins with a straightforward dough that requires just five ingredients and minimal hands-on time. After mixing, the dough rests in the refrigerator overnight, where the slow fermentation enhances flavor and improves digestibility.

The next day, shaping and baking take less than 30 minutes, with precise oven temperature control ensuring a perfect rise and golden-brown crust every time.

What sets this recipe apart is its reliability—no guesswork about hydration levels, proofing times, or oven temperatures. The dough's high hydration creates that signature open crumb, while a steam bath during baking produces the coveted crispy crust.

The result is a loaf so good, you'll never buy store-bought bread again, with each slice offering a perfect balance of chew and tenderness.

Ideal for beginners and experienced bakers alike, this recipe scales perfectly for sandwiches, toast, or French toast. The long fermentation also makes it easier to digest than traditional yeast breads. Let's get started with this game-changing technique that transforms your kitchen into a bakery.

Ingredients for america's test kitchen bread

Five simple ingredients transform into restaurant-quality bread with just 24 hours and precise technique.

The flour makes all the difference here—King Arthur or Bread Flour from Williams Sonoma delivers the best gluten development for that signature open crumb. If you're using all-purpose, sift it first for consistency. The yeast should be fresh: if it's over a year old, proof it in warm water before using. Diamond Crystal kosher salt is crucial—it dissolves more evenly than table salt, preventing flavor imbalances. For the olive oil, California Extra Virgin brands like Corto or Kirkland offer the right balance of fruitiness without overpowering. Water temperature matters: too hot kills the yeast, too cold slows fermentation—aim for room temperature.

No instant yeast? Active dry yeast works if proofed in warm water for 5 minutes first. Running short on olive oil? Avocado oil or vegetable oil are neutral substitutes, though they lack the subtle flavor. The sugar can be swapped for honey (same amount) if you prefer, but it may darken the crust slightly. For the steam bath, if you're without ice cubes, a metal bowl of boiling water on the oven floor works just as well. The cornmeal is non-negotiable for that crispy bottom crust—don't skip it. And if your kitchen feels too dry, cover the dough loosely with plastic wrap during fermentation to retain moisture.

The dough is best baked within 48 hours of mixing, though it can ferment up to 72 hours in the fridge for deeper flavor. Store any leftovers in an airtight container at room temperature for 3-4 days, or freeze for up to 3 months wrapped tightly in plastic. For reheating, wrap slices in foil and warm in a 350°F oven for 5 minutes to restore freshness. This bread freezes beautifully—portion before freezing for perfect single-slice thawing. The longer it ferments, the more digestible it becomes, making it ideal for sensitive stomachs.

Step-by-step instructions for america's test kitchen bread recipe

This method delivers a crusty, open-crumbed loaf with minimal effort—just follow these precise steps.

In a large bowl, combine the 4 cups all-purpose flour, 0.25 tsp instant-release yeast, 0.5 tsp granulated sugar, and 1.5 tsp diamond crystal kosher salt. Whisk briefly to distribute the yeast and sugar evenly through the flour—this ensures even activation later.

Add the 0.5 cup extra-virgin olive oil and 1.5 cups room-temperature water to the dry ingredients. Using a wooden spoon or dough whisk, mix just until the ingredients come together into a shaggy mass. Avoid overmixing—this prevents gluten development and maintains the bread's open crumb structure. The dough will be sticky, which is normal for this no-knead method.

Cover the bowl tightly with plastic wrap or a damp kitchen towel. Let the dough rest at room temperature for 12-18 hours. This extended fermentation develops deep flavor and allows the gluten to relax naturally. I place my bowl in a slightly warm spot (around 70-75°F) to encourage even fermentation without overproofing.

After resting, the dough should have risen noticeably and expanded to fill about 75% of the bowl's volume. Press your finger gently into the dough—it should spring back slowly rather than immediately, indicating proper fermentation. If the dough hasn't risen significantly, it may need another 4-6 hours at a slightly warmer temperature.

Lightly flour a clean work surface and gently turn out the dough. Shape it into a rough oval by folding the edges toward the center and stretching the dough slightly. Place the shaped dough seam-side up on a parchment-lined baking sheet. Dust the top generously with 0.25 cup cornmeal—this creates the signature crisp crust and prevents sticking.

Cover the baking sheet loosely with plastic wrap and let the dough proof for an additional 1-2 hours until it has risen to nearly double in size. The edges should pull away from the baking sheet slightly, and the dough should feel light and airy when pressed gently. This final proofing ensures proper oven spring during baking.

Preheat your oven to 450°F with a baking stone or inverted baking sheet on the middle rack. Once preheated, place 1 cup ice cubes in a small heatproof bowl and position it on the lower oven rack. This creates a dramatic steam burst when the oven opens, which is essential for developing that signature crisp crust.

Carefully slide the dough into the oven (use the parchment for easy transfer). Bake for 30 minutes, then reduce heat to 425°F and continue baking for another 20-25 minutes until the bread is deep golden brown. The internal temperature should reach 190-195°F when measured with an instant-read thermometer.

Remove the bread from the oven and transfer it to a wire rack. Let it cool completely for at least 1 hour before slicing—this allows the crumb to set properly and prevents a gummy texture. The crust should be crisp and shatterable, while the interior should have an open, airy crumb with occasional small holes.

Slice the bread with a serrated knife for clean cuts. Serve warm with butter or olive oil for the best experience. This method consistently produces a rustic, flavorful loaf with minimal effort—perfect for any home baker.

Flavor customization for america's test kitchen bread

Herb-Infused Variations

Add 1 tbsp fresh rosemary or thyme to the dough during mixing for a fragrant Mediterranean twist. I like to finely chop the herbs and fold them into the flour before adding wet ingredients.

For a heartier flavor, use 2 tbsp dried herbs instead. These additions work especially well with olive oil—try Italian extra virgin brands like Filippo Berio for deeper flavor. 🌿

Seeded and Nutty Crust

Mix 2 tbsp sesame seeds, 1 tbsp flaxseeds, and 1 tbsp sunflower seeds directly into the dough for a nutty, crunchy texture. For extra richness, add ¼ cup chopped walnuts or pecans.

Toast the seeds and nuts in a dry pan for 3 minutes before mixing to intensify their flavor. Sprinkle them on top before baking for maximum crunch.

Sweet Loaf Adaptations

Swap 0.5 tsp granulated sugar for 1 tbsp honey or maple syrup to create a lightly sweetened loaf. Add ½ tsp cinnamon or cardamom for warmth.

This version works beautifully with blueberry or chocolate chip swirls—fold in ½ cup mixed berries or mini chocolate chips during the final shaping step. The sweetness balances perfectly with the bread's rustic crust.

Whole Grain Boost

Replace 1 cup all-purpose flour with whole wheat flour or spelt flour for a nuttier, denser crumb. For a lighter texture, use half whole grain, half all-purpose flour.

Whole grain versions benefit from an extra 30 minutes of room-temperature proofing before baking. Pair with olive oil and sea salt for a rustic, artisanal flavor.

Garlic and Cheese Enhancements

Add 2 minced garlic cloves and ½ cup shredded Parmesan cheese to the dough for a savory, umami-rich loaf. The garlic infuses deeply during fermentation, creating a subtle yet noticeable flavor.

For extra richness, use Pecorino Romano instead of Parmesan. This variation pairs perfectly with soups, stews, or as a side for hearty meals.

Spiced and Smoky Options

Incorporate ½ tsp smoked paprika or 1 tsp cumin for a smoky depth. For a sweet-and-spicy twist, add ½ tsp cayenne pepper along with 1 tsp brown sugar. These spices work especially well with olive oil and sea salt for a rustic, flavorful loaf.

The spices enhance the bread's crust and crumb, adding complexity to every bite. 🔥
